Diversity is vitally important within the Linux world. For example, rather than just one e-mail program, you’ll find many available. They compete with each other in a gentle way, and it’s up to you which one you settle down with and use. Part of the fun of using Linux is exploring what’s available. Of course, the added bonus is that virtually all this software is free of charge, so you can simply download, install, and play around. If you don’t like a program, just remove it from your system. However, don’t forget to revisit the program’s home page after a few months; chances are the program will have been expanded and improved in that short period, and it might be better at meeting your needs.

OUTPUT If you’ve read any of the Ubuntu man pages, you might have seen references to standard input and standard output Like many things in Linux, this sounds complicated, but is merely a long-winded way of referring to something that is relatively simple (although the terms have specific meanings to programmers) Standard input is simply the device that programs running under Ubuntu normally take input from... itself, and some users of Linux treat it as their shell, executing commands and performing everyday tasks, such as reading and sending e-mail from within it There are entire books written solely about Emacs and Vim ■ Tip A fourth shell-based text editor found on many Linux systems is nano This offers many word processor–like features that can be helpful if you’ve come to Linux from a Windows background... it’s generally agreed that Vim offers substantial text-editing power but isn’t too all-encompassing It’s also installed by default on Ubuntu On Ubuntu, Emacs must be installed as an optional extra Both text editors are normally available on virtually every installation of Linux or UNIX We’ll concentrate on using Vim here 269 CHAPTER 12 ■ WORKING WITH TEXT FILES It’s important to understand that Vim is... mentioning that text files under Linux usually don’t have a file extension Unlike with Windows or other OSs, the txt file extension is rarely used Sometimes a conf extension is added to plain text configuration files, but more often text files have no extension at all Text: A History Lesson Given this reliance on text and text files, it has always been very important for Linux administrators and power... hardly replaced by graphical interfaces or fancy touchscreens These tools can be imitated, but never replaced Like many other features of Linux, they have been inherited from UNIX Just as a reference, let’s introduce you to some of these tools; should you ever become an Ubuntu guru, you’ll learn how to use them in more depth and you’ll become a huge fan Guaranteed! Table 12-1 List of Traditional Text-Manipulation... and the Emacs vs vi debate is considered an entertaining cliché of Linux and UNIX use When users declare online which text editor they prefer, they often include a smiley symbol to acknowledge the once-fevered emotions Working with Text Files Fortunately, you don’t need to learn how to use those tools if you don’t feel like it, because Ubuntu comes equipped with a powerful, and yes, graphical, text-editing... WITH TEXT FILES ■ Note The less and more commands are sometimes known as pagers because of their ability to let you scroll through pages of text You might still hear them referred to as such in the wider Linux community, although the term has fallen out of use Bash is an incredibly capable tool when it comes to text manipulation, and some of its tool set offers modest word processing–like functionality... if the word is displayed in the output, the word has been found If not, the word hasn’t been found Note that this command returns loose matches—searching for test, for example, will return every word beginning with test (testing, testimony, testosterone, and so forth) Word count wc -w filename Outputs the number of words in filename Used without the -w command switch, wc outputs the number of lines, .
